Applicant inea october s, 189e.

To a/ZZ whom; jtm/ay concernf Be it known that I, CHRISTIAN EISENBERG, asubject of the :Emperor of Germany, residing in Berlin, Kingdom ofPrussia, Empire of Germany, have invented 'certain "new and usefulImprovements in 'Pulling- Over and Fastening Machines for Shoes, ofwhich the following is a specification. K- v This invention consistsin amachine which takes the place of the pegging-machine used inshoemaking;H and its object is to unite the inner sole provisionallywith' the upper, which for this purpose 'is providedI with anoutwardlyextending rim.` The inner sole is united with this uppery bydrawing pins or pegs, which after the sewing of the-sole iscompleted'ca'nfbe withdrawn.

In the accompanying drawings, illustrating the machine whichifornls thesubject of my invention, Figure 1 is a topviewof the machine, someofythe parts being broken away to make the construction'clearer." Fig'.- 2is a similar View to Fig. 1, the parts, however, being shown in theoperating position, while inFig. 1 they are in a nonfoperating position.Fig. 3 is a front elevation of the machine. Fig. 4 is a vertical sectionthrough the machine. Fig. 5 shows in plan view the pedalwork of themachine, thetableabove' same being removed. Fig.` 6 shows a pressingdevice used in the machine." Figs. 7 and 8 show the fastening devicesfor y the vlast holder. Figs. 9 and lOyshow the last-holder in top'andside views. "Fig 9a shows alsection of a part of the last-holder. Figs.'lland 12 show further details of thel pressing device. Figs. 13 and 14show the pressing and driving device for the toe of theshoe. Figs. 15land 16 show the fastening nails or pins. Figs. l17 and 18 show astretching-clamp in top and side views. Figs. 19fand' 20""show detailsof a modified form ofpressinggdevice. Figs. 21 and' 22 serial No.607,771. (No mtas.)

block b, which carriesclips or catches c. Into these catches are pushedthe fastenings or hooks d with which the metal sole-plate or last-holdere is provided. a

, In the block is a draw bar or bolt f, provided at its` forward endwitha folding handle and heldv by a spring in position to allow the hooks dto be pushed freely into the catches c. The metal sole-plate 'e havingbeen placed in position on the block, the draw bar or bolt f is drawnforward and a'nose f' thereby brought behind the rear hook d, so thatthe metal solepljate eis thereby fastened rigidly to the block b. Aset-screw]E2 insures this fastening. On the metal sole-plate e a last isnow placed carrying the upper orv shoe-body g and the inner sole. Thefastening, of same can v conveniently be eifecte'd bymeans of screwsVpassing through holes provided in the inner'sole, the said holes beingafterward closed up.

At the lower part of the machine are the pedals h h h2, which areconnected with the three bars Il 'i' i2. There are also (see Fig. 5)four other bars lo 7.o k2 k3 in the Inachine,which can be connected withthe pedals h h2 by the following devices: Around the bars t" and t2,

belonging to 'pedals hand 71.2, swing an gie-,arms v Z and Z,which bymeans of appifopriate` notches can be `connected one with either bar 7eor bar k3, the other with either bar 7c or bar 7a2. If,

as shown in Fig. 5, by throwing the angle-arm Y metal sole-plate e thestretching-clampsv (shown inwFig's. 17 and 1S) are placed onpappropriateparts of the upperg. ,Theshe'arnlike lconstruction of these clamps issuch that wh'euwtheya're pulled the leather is tightly gripped, but isvreadily released on withdrawing the tension. These stretching-clamps,

which are connected with bars i and la in any suitable manner,enable theupper to be drawn tight 'over' the last by the operation of the Ioopedals 71 7L h2. Binding or clamping frames O O, corresponding in shapeto the two sides ot the sole, are supported so as to slide crosswise ofthe table u and are moved by screwspindlcs operated by hand-wheels n.The upper having been pulled tight over the last, as above described,the frames O O are operated in opposite directions by hand-wheels n, soas to be brought up tight against the upper, impartingto it the shapeshown in Figs. 21 and 22.

On each fra-me O stands a row of driving devices or jacks p, (shown indetail in Figs. 1l and 12,) each having a pin-holder or nailholderp. lnthese pin-holders the U -shaped or staple-shaped pins or nails shown inFigs. 15 and 16 are pressed downward by springs. These springs arecarried by caps held in place by catches. Each driving device p has atone end a bent lever q, engaging with a slide or bolt workin g beneaththe pin-holder, so that when the upper arm of said lever is depressedits lower arm engages with the bolt yr, which takes a pin or nail fromthe pinholder and drives it out horizontally. rlhis causes the pin topenetrate the sole and upper in about a horizontal direction (orsubstantially parallel to the bottom of the shoe) and forces it iinallyagainst the metal soleplate c. By means of round. depressions s in themetal sole-plate the inner ends of the U- shaped pins are bent inwardlyor toward one another, thus for the time being uniting or bindingtogether the inner sole and upper at those points. lVhen the upper armof lever q is released, a spring throws back the bolt/'1l and allowsanother pin to fall into position to be driven out.

In Fig. C is shown a device which enables all et the levers q on oneside to be operated by a single movement, and thus by means of the twohands to complete the binding together of the shoe by one movement. Forthis purpose a frame t is placed over all of the levers q, the samebeing pressed down by the hand-lever f, acting through the cam 2. rlhecam t2 is pivoted in the trame of the machine and engages with across-bar connected to the frame t, as shown in Fig. (i. rlhe operationis such that as both the frames t move downward the angle-levers q turnon their pivots, the bolts rare all shot out, and a complete set of pinsor nails is placed in the shoe except atthe toe, where this drivingdevice is not present; but a special arrangement (shown in Figs. 113 and1l) is provided. In this a small pin (shown in Fig. 1G) is lixed in apineers u, carried by a holder sliding in a support on the frame. Thenthe latter, by means o hand -crank u', acting on a screw on the holdercarrying the pincers, is brought against the shoe, and then through ablow on the press-button u? the clip is driven through the shoe-toe andthere fastened. rlhe frames O are then withdrawn from the pinned shoe byturning baci; the hand-wheels u, the last is released by loosening thesetscrewf?, the boltfilying back, and the nesef' being removed from thehookd. rlhe last is then removed from the metal sole-plate c, which isthen ready to receive a new last. The shoe pinned together in thismanner is then sewed in any desired way,.vhereupon the fasteningpinshaving become superfluous are withdrawn. The partly-iinished productthus obtained is then operated upon in any suitable manner, so as tofasten the under sole and heel to it and p ut it in merchantablecondition.

To enable proper operation of the machine, it must of course be providedthat the working surface of the frame O, surrounding the upper, is instrict correspondence to the form of the sole, as the pin-holders p muststand in such positions that they are always opposite the line of Linienof inner sole and upper. It is clear from this that in case ot anychange in the form of the sole the trames O, and as a consequence theframes t, must be changed 0r else made to frt by the insertion ofsubstitute parts. In Figs. 19 and 2O is shown a device by which thischanging over or insertion of iitting pieces is rendered unnecessary.rlhe frame O is here so far changed that each pin-holder, together withthe portion of the frame belonging to it, is separately mounted from theothers. All these pin-holders here rest directly on the support e, whichis opel.'- atcd by hand-wheel n. rl`he pin-holders y, which in this casecorrespond to workin g sections ot the frame O, each carry a little noser', that is intended to bend the upper, as shown in Figs. 21 and rlhesepin-holders are supported from supports t' by means of adj usting-screwsw, to which they are joined by a universal joint, thus enabling theirdistance from the sole-plate to be changed. A frame as is arranged onthe side of support e and carries adjusting-screws 7], by which theheight of the pin-holders relative to the soleplate is adjusted. lf nowa sole of a difterent form is introduced, the pin-holders p arc iirstbrought up to the sole by means of handwheels yn and then adjusted byoperation ot the three adjusting-screws w 1/ exactly to the curves ofthe sole. It then the two supports yr are drawn back, a last with upperand inner sole placed on the sole-plate and the handcranlis u. againoperated, each pin-holder will strike exactly on the proper spot andwill,by means of the nose fr', bend the upper as desired, the driving ofthe pins being effected, as before, by a iframe and hand-lever.

llaving thus described my invention, the following is what l claim asnew therein and desire to secure by Letters Patent:

1. A machine for manufacturing shoes, comprising a last-holder,stretchirig-clamps, devices for drawing down said clamps, tramescorresponding in shape to the sides of the sole, and devices forbringing said frames up to said sole, and pin-driving devices mounted insaid frames and adapted to d rive pins through the inner sole and upperin directions substantially parallel to the bottom. of; the shoe.
